Input File Documentation¶
There are two input files that need to be defined to use the GeoJSON to Modelica Translator: a GeoJSON file and a System Parameters file.
GeoJSON Documentation¶
Presently only the building_properties.json of URBANopt’s GeoJSON schemas is leveraged in the GMT.
Building Properties¶
Bolded elements are required fields.
